Printer Maintenance Parts
Drum units, waste toner bottles, fusers and maintenance kits — the consumables that are not toner but stop the machine just as firmly when they run out. Print faults that survive a cartridge change are almost always the drum; a colour laser will refuse to print at all once the waste bottle fills, whatever the toner level says.
Both are scheduled parts with a stated page life, so keep one spare of each for any machine the office genuinely depends on. See toner cartridges, printer ribbons and printing supplies.
